1) Slowly varied dielectric
缓变介质
2) medium with smoothly varying stiffness
刚度缓变介质
1.
The results show that when a medium with smoothly varying stiffnesses is modelled with a layered medium in the back-analysis of the measured dispersion data, the match between the measured and the theortical dispersion data and the calculated stiffness profile are influenced by number of layers.
基于薄层刚度矩阵方法,研究了瑞利波在3种典型刚度缓变介质中传播特性,并对瑞利波在缓变介质及分层介质中传播特性进行比较。
3) medium with gradual transverse change in velocity
横向缓变介质
4) buffer media
缓冲介质
1.
Results show that formic acid is the bestselection as the buffer media for the determination of RE by arsenazoⅢ colouring.
比较研究了甲酸、乙酸和一氯醋酸三种有机酸溶液对稀土－偶氮Ⅲ显色性能的影响，结果表明：在用偶氮Ⅲ显色测定稀土时，选择甲酸溶液作缓冲介质最好。
5) diazaquinon
无缓冲介质
6) deformable media
变形介质
1.
And the media deformation is elasticity-plasticity deformation process,so the pressure must be kept above one certain level in reservoirs with deformable media during the early stage of exploitation.
从流体和多孔介质的本构方程出发,建立液体在变形介质油藏中渗流的微分方程。
2.
In the process of developing deformable media gas fields, the pore pressure decreases when fluids flow out of the reservoir, and the difference of pressure inside and outside the reservoir increases.
变形介质气藏在开发过程中 ,孔隙压力随流体的流出而下降 ,使储层内外压差增大 ,孔隙受到压缩而体积缩小 ,孔隙度和渗透率随之降低 ,极大地影响到此类气藏的开采。
补充资料：缓变pn结（gradedp-njunction）
缓变pn结（gradedp-njunction）
从p区到n区掺杂浓度逐渐改变的pn结，如用固态扩散工艺制造的pn结。大多数缓变pn结数学上可作为线性缓变结处理。通常由扩散工艺制备的pn结为缓变pn结，但在浅扩散结或高反偏时它更接近于单边突变pn结。
